(Springer, 2021-03-08)
Purpose This study aimed to test the activity of Mn ferrite, hematin-Mn ferrite and colloidal maghemite in decomposition ofOrange II (O-II) and Alizarin Red S (ARS) in model aqueous solutions.Methods Color removal was ...
Permeability of human red blood cell membranes to hydrogen peroxide
(Cell Press, 2020)
Hydrogen peroxide (H2O2) and other reactive species are important physiological mediators in the vascular system. Enzymatic production of H2O2 is involved in regulating cell growth, proliferation and vasodilation. Whereas ...
AFM study of oxygen reduction products on HOPG in the LiPF6–DMSO electrolyte
(Royal Society of Chemistry, 2013-12)
Ex situ atomic force microscopy (AFM) has been used to study the morphology of oxygen reduction products in the LiPF6–dimethyl sulfoxide (DMSO) electrolyte, i.e. Li2O2 on a highly oriented pyrolytic graphite (HOPG) surface. ...
Immunomodulatory Effects of Palladium(II) Complexes of 1,2,4-Triazole on Murine Peritoneal Macrophages
(Soc Brasileira Quimica, 2009-01-01)
The 1,2,4-triazolyl-bridged polynuclear complexes [{PdCl(2)(mu-Htrz)}(n)] (1) and [{PdBr(2)(mu-Htrz)}(n)] (2) have been obtained in this work. Compound 1 is prepared by the displacement of acetonitrile from [PdCl(2)(MeCN)(2)] ...

Kinetics of Ep stage in kraft pulp ECF bleachingCinética do estágio Ep no branqueamento ECF de polpas kraft
(Associação Brasileira Técnica de Celulose e Papel, 2009-06)
The purpose of bleaching is to eliminate the groups responsible for pulp colour. These chromophoric groups are eliminated or transformed by means of chemical reactions. In alkaline stages reinforced with hydrogen peroxide, ...
Thermal Decomposition of Diphenyl Tetroxane in Chlorobenzene Solution
(Scientific Research Publishing Inc., 2019-01)
The thermal decomposition of Cyclic Diperoxide of Benzaldehyde 3,6-diphenyl-1,2,4,5-tetroxane, (DFT) in chlorobenzene solution in the studied temperature range (130°C - 166°C) satisfactorily satisfies a first order law up ...
